An oral formulation, which can form micelle-like vehicles, can be used to overcome the malabsorption of these nutrients in CF patients. A pilot study of a prototype formulation showed both safety and efficacy in increasing systemic levels of target nutrients. This study will test the safety and efficacy of the final commercial formulation (AquADEKs) in the form of a softgel capsule in increasing the plasma levels of certain nutrients and antioxidants.
